Application filed December 21, 1910. Serial No. 598,609;

To all whom it may concern:

Be it known that I, CHARLES J. HEINE- MAN, citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Wind-Shield Cleaners,of which the following is a full, clear, concise, and exact description.

The glass shields ,for automobiles are generally set in a frameconsisting of round metal tubing; the driver sits back of the glass andis dependent upon its transparency for his view in directing the courseof the car. Distinctness of vision is therefore dependent upon keepingclean the glass immediately in front of the drivers position. Provisionmust therefore be made for wiping the front face of the glass to removedust and mud that are liable to accumulate at all times, and snow, whichin winter, will often quickly gather so as to completely cover the frontof the glass- While attempts have been made looking toward a device tobe carried on the .wind shield and operated for this purpose, I know of.no. structure prior to my invention that has fully or inany'waysatisfactorily met the conditions.

Myinvention may be characterized as an automatic squeegee for windshields. The frame carrying the strip of rubber which is to be wipedbackand forth at will over the front surface of the glass is providedwith aguiding clamp adaptedto be mounted upon the upper tube or sash ofthe glass and to be moved backand forth thereon. The strip of rubber orwiper ispivotally mounted upon the lower end of a rod depending from theguide; the said rod extending to the other side or backof the glass andprovided there with a spring stud adapted to press against and ride uponsuch back surface of the glass and thus hold the rubber strip firmly inwiping contact against the front surface thereof as the guide ismove'dback and forth inthe act of cleaning.

It should be remarked that an important feature of my invention consistsin the construction whereby therubber strip is pivot ed soas toautomatically adjust itself not only horizontally to bring the stripinto wiping engagement with the glass as the direction of the movementthereof is reversed; but also to a slight extent vertically so as tocause the squeegee strip to adapt itself to any unevenness in thesurface that is being cleaned.

My invention will be more readily understood by reference to theaccompanying drawing, in which:

Figure 1 shows my cleaner mounted on the wind shield and in position ofuse when being moved to the right; Fig. 2 is a side elevation thereof inthe same position, the shield being shown in transverse verticalsection; Fig. 3 is a plan taken on line 3 of Fig. 2; Fig. 4 illustratesin detail the pivotal connection of the squeegee back with the dependingrod of the movable carriage as seen from. line 4.4 of Fig. 2; Fig. 5 isa sectional detailed view of the spring stud which rides on the backsurface of the glass, taken on line 55 of Fig. 1; and Fig; 6 isanenlarged side view of the pivotal connection of the squeegee with thedependmg arm upon the section line 6-6 of Fig. 1.

Like parts are indicated by similar characters of reference in thedifferent figures.

The rubber strip 1 with the back or metal mounting 2, taken together,may be termed the squeegee. My invention consists essentially incombining with the. squeegee, mechanism for readily mounting the sameupon the shield and for enabling the chauffeur conveniently andefliciently towipe ofi the glass from'time to time as may be required.The angle of the strip of rubber to the plane of the surface should besuch that the working edge will be bent so as to give a frictionalbearing surface of say about half an inch in width; the angle beingautomatically changed from left to right right to left as the squeegeeis carried back and forth. This movement is obtained by pivotallymounting the back 2, preferably atfi'about midway of its length to thedepending end of the rod 3 of the carriage 4. The mounting may consistof the loop so stud to from the other side thereof.

or clip 5, the pin 6, passing through the to The corresponding loop orclip 8, as clearly shown in Fig. 3, has an oblong opeg which permits acertain vibration baclr and forth ofthe squeegee so that no matter inwhich direction it may be moving overthe I surface of the glass, theworking edge thereof vvill. conform to any unevenness or curvain thesaidsurface. The member 9 of the carriage may con sist, as shown, of thehalf tubular part lll 2a and the corresponding part 11 hinged thereto,the said part 11 being of about one-half the width of the correspondingpart, that is to say, there is left in the member 9 an open slotsomewhat wider than the thickness of the glass. The portion 10 isprovided with extension 19, on which is rigidly mountthe yolre 13. Therod 3, previously men-- tioned, depends from one side of this yoke, andthe curved rod M carrying the spring it will seen that in this instancethe vrods or legs 3 and it are integral and at the upper por-- tionrigidly secured to the yoke, the yoke in turn being rigidly secured tothe entension l2.

' will be seen that the construction ofthe' carriage is such that whenin place it may readily be moved by the chaudeur back and forth, the rod1% serving as a handle; at the to same time the carriage will be free torotate to a slight extent to permit the squeegee to conform to thesurface being cleaned, in wiping engagement. p it should be noted thatthe counter open-- 14.5- mg 7 in red 3 for the pin 6 is counter sk so asto permit the automatic reversal position of the squeegee when thedirectron of the movement of the carriage is phanged, while, at the sametime, the worka Edi-mg edge of the strip must follow the surface beingcleaned. 4 ltwill be understood that the mber 9 -mustconform to theshape of the frame or -other part of the shieldv on which it is pmounted. llnthis instance it is made cylin 7 drical and With. an openslot and so con structed as to be readily placed in position for useandremoved again when no longer required;

. lhe force of the spring l6 stud 15 .1 should be suficient to cause thesqueegee to press against .the front of the glass -r,wh 1le at the sametime adapted to yield me ex e nitr te...)

.sufficiently to permit the squeegeeto turn back and forth to come intowiping engagement with the glass each time the direction of the movementof the carriage is re- .versed.

The rod it is preferably curved to one side of a. vertical plane inorder that by turning the device slightly toone side, in

the framathe device is then turned into proper position to fit upon theupper edge of the frame. it will also be noted that the plunger 15 actsas a stop to prevent the carriage being inadvertently carried so far asto slide elf the ends ofthe wind shield.

The rods 3 and it are preferably rounded as shown in Fig. 2 in orderthat when the wind shield is folded in the usual welllmown manner thecorresponding portion of the lower frame may fit against the end curvedportions 3 or 14 respectively, depending upon whether the shield isfolded outside or inside.

. My invention admits of-various modifications that will readily suggestthemselves to those skilled in the art and l therefore do not wish toconfine'myself to all the details of the structure shown.
